When you become a DC-3 Dreams customer, you get an account here on the Comm Center with the user name set to your real name (as opposed to a computer username). It's so much nicer to see "Bill Daley" under your picture instead of something like "dal54xyz".
If you currently have a computer username for a name here, you can change it to your real name. After doing so, you will need to re-log-in using your real name as your user name.
To change your user name, go to the User Control Panel (User C/P button in the button bar at the top), then select edit email, password, and user name along the left edge. See the attached screen shot.
Be careful, you only get one chance. And don't forget to log off then back on with your new user name.
